Abstract

A portable device includes an active device (communication station) configuration for contactless communication with at least one external data carrier and a passive device (data carrier) configuration for contactless communication with at least one external communication station. A detection circuit is provided to detect the presence of an external data carrier and/or the presence of an external communication station in a communication zone of the internal active device configuration and/or the internal passive device configuration. An activation circuit is coupled to the detection circuit to enable one of the two configurations based on the detection result.

Claims17

Dependent claims

A portable device comprising:

an active device configuration, within the portable device, that is configured to provide contactless communication with an external passive data carrier,
a passive device configuration, within the portable device, that is configured to provide contactless communication with an external active communication station,
a detector, within the portable device, that is configured to detect a presence of either the external data carrier or the external communication station, and
an activator, within the portable device, that is configured to selectively activate the active device configuration if the external data carrier is detected, and the passive device configuration if the external communication station is detected.
